24/7 Wall St.

Stocks opened lower this morning and trailed mostly lower throughout the day. Today’s wholesale inventory reported showed a gain of 1.6% and the initial jobless claims were substantially lower than expectations of 395,000, at 381,000. The two reports probably cancelled each other out as word hit the street that Europe is forecasting weaker growth and that today’s expected interest rate reduction was agreed with less than a unanimous vote by the ECB. The stress test results for European banks were released today, causing shares in some European banks to fall. WTI crude has fallen by more than $2 to $98.33/barrel and Brent crude is also down by about $1.65 at $107.86. Gold is down nearly -2%, at $1,710.40.

The unofficial closing bells put the DJIA down more than 198 points to 11,997.93 (-1.63%), the NASDAQ fell nearly 53 points (-1.99%) to 2,596.38, and the S&P 500 fell -2.11% or nearly 27 points to 1,234.35.
